- The following glassware is used when we do titrimetric analysis. If the glassware is not fully dry when used (i.e., there is water left in the glassware), determine whether this will affect the results of the titration process. Give a brief explanation. a. Erlenmeyer flask (used during titration) b. Burette c. Pipet (used in transferring the sample) d. Volumetric flaskUse some or all the data below to calculate the concentration of acetic acid (in M) in the Walmart bottle. Remember 1 molecule of NaOH neutralizes 1 molecule of acetic acid. Assume you titrated a 100.00 mL solution containing 1.00 mL of the Walmart vinegar. Data: Concentration of NaOH: 0.08467 M Titrant initial buret reading: 30.21 mL Final buret reading: 38.37 mLVolumetric Analysis Liza carefully pipets 25.0 mL of 0.525 M NaOH into a test tube. She places the test tube into a small beaker to keep it from spilling and then pipets 75.0 mL of 0.355 M HCl into another test tube. When Liza reaches to put this test tube of acid into the beaker along with test tube of base, she accidentally knocks the test tubes together hard enough to break them and their respective contents combine in the bottom of the beaker. Is the solution formed from the contents of the two test tubes acidic or basic? What is the pH of the resulting solution?

- To analyze an aspirin sample, 0.3470 g of crushed tablets are weighed and treated with 50.00 mL 0.1155 M sodium hydroxide, boiling for 10 minutes. Under these conditions the acid acetylsalicylic (MW, 180) reacts according to: CH3COO-C6H4-COOH + 2 OH- → OH-C6H4-COO- + CH3COO- The excess NaOH is then titrated with 11.5 mL of 0.2100 M HCl. What is the purity of said show ?.What acid-base indicators, shown in Figure 18.24 would be suitable for the neutralization reaction whose titration curve is shown in Figure 18.30?Why?Consider an impure sample of 25.20% Na2CO3. How many grams of the sample must be dissolved in a 500-mL solution so that titration of a 50-mL aliquot portion will require only about 22.0 mL of 0.1250 M HCl to reach the methyl orange end point?
